You may want to look into getting a better wifi adaper as it seems kind of waste to only spend $10 on one when it's a very high budget build

Go for the 4670k as you don't need the 4770k

Only get 8GB of 1600MHz RAM as 32 is way overkill

That last two points do depend however on what you mean by multimedia. If it's like video editing and stuff than you probably do need those things but otherwise you most likely won't so do some research on that.

2 780s or one Titan provides more VRAM than the 690 which is better for multimonitor gaming. Also, the 2 780s is more powerful than the 690 as the 690 is just two 680s in one card whereas the 780 is basically a stripped down Titan

Windows 8 is superior to Windows 7 and provides better multimonitor support, which you'll be using

Not necessarily but some more expensive ones may have more antennas or a better range or a better throughput speed or something

Unless you'll be doing lots of multithreaded processes the 4670k and the 4770k will provide the same performance so why pay more for a feature you won't use?

My concern is SLI driver updates. Are nVidia good about staying on top of those?

Good point.

I'll go back and look at reviews.

Is that rendering and the like? I really just want to overclock. Thanks for your help, btw!

Oh you don't need a card that does 192 khz for that, that's the sample rate. I can imagine the surround sound set up comes with all the neccesary cables. Each speaker connected in series and then just take the 3.5mm out from the computer's sound card to the amplifier. Any sound card will work but the human hearing range (and what most speakers put out) is only between 20-20kHz. This means any audio in anything above 48kHz or so starts to become unnoticeable. If you want a good sound card invest in one with a good quality pre-amp.
